Investigation Of Ramp/Cowl Shock Interaction Processes Near A Generic Scramjet Inlet At Hypersonic Mach Number
(2010-08-05)One of the major technological innovations that are necessary for faster and cheaper access-to-space will be the commercial realization of supersonic combustion jet engines (SCRAMJET). The establishment of the flow through ... -
Investigation of sea level anomalies along the Indian coastline using tide gauge data: a physics-guided machine learning approach
The Indian coastline falls within low-elevation coastal zones that are densely populated. Recent observations indicate, with high confidence, that the rate of sea level rise in the In- dian Ocean has been accelerating ... -
An investigation of the role of buoyancy in magnetic polarity transitions in rapidly rotating dynamos
The dynamo operating within the Earth’s outer core generates a predominantly north-south dipolar magnetic field. Occasionally, the magnetic dipole axis flips its orientation and retains its approximate alignment with the ... -
An investigation of the sensitivity of climate feedbacks to the latitudinal distribution of radiative forcing using the radiative kernel approach
It is well known that climate sensitivity, defined as the global mean surface temperature change per unit radiative forcing, depends on the forcing agents (such as CO2, CH4, O3, aerosols, solar radiation, land cover change, ... -
